Abstract
Description
Technical Field
[0001] The utility model belongs to an experimental table, in particular to a chemical analysis experimental table for geological experiment testing. Background Art
[0002] Geological experimental testing is a series of chemical or physical measurement operations performed on mineral samples obtained during geological surveys in the laboratory. In the early stages of geological work, experimental testing is the main basis for judgment in geological work. The results obtained from geological experiments are an important experimental basis for data generation in testing work. Geological experimental testing requires the addition of chemical agents to mineral samples to obtain experimental data. Therefore, a liquid positioning device for geological experimental testing is needed to add chemical agents to ore samples.
[0003] The laboratory exhaust system consists of three parts: the air intake system, the exhaust system and the air duct system. The air intake system mainly introduces external gas into the laboratory, usually through air purifiers and other equipment to filter and purify the incoming air. The exhaust system discharges waste gas and pollutants from the laboratory. The exhaust system is usually composed of an exhaust fan, an air duct and an exhaust pipe, among which the exhaust fan is the core part. Its main function is to suck the harmful gas, dust or odor generated in the laboratory into the exhaust system and discharge it out of the laboratory.
[0004] The existing technology has the following problems: the exhaust system is fixed at a certain position in the laboratory. The exhaust system sucks out the gas in the laboratory and sends external air into the laboratory. By maintaining the pressure difference between the inside and outside of the laboratory, harmful gases leave the laboratory. Since the space is too large and the exhaust system is at a certain distance from the experimental location, harmful gases cannot be removed in time, increasing the probability of contamination of experimental supplies.

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.
[0030] Reference Figure 1-7 As shown, a chemical analysis test bench for geological experiment testing includes a table body 1, on which a storage cabinet 2 is arranged. A plurality of placement cavities 4 are arranged in the storage cabinet 2. The placement cavities 4 are arranged longitudinally, and the outer side of each placement cavity 4 is rotatably connected to a baffle 6 via a rotating shaft 5.
[0031] An exhaust device 3 is fixedly installed on one side of the table body 1. The exhaust device 3 includes an air inlet pipe 14 and a translation component. The air inlet pipe 14 is connected to a telescopic pipe 13, a curved pipe 12, an air supply pipe 11, a hose 15 and an exhaust fan 16 in sequence.
[0032] The translation assembly includes a main body 7 and a slide plate 10. A slide groove 8 is provided on the upper surface of the main body 7. A guide rod 9 is fixedly installed on the inner wall of the slide groove 8. The slide plate 10 extends into the slide groove 8 and is slidably connected with the guide rod 9. The air pipe 11 is fixed on the slide plate 10 so that the air pipe 11 moves with the slide plate 10. The translation assembly drives the air intake pipe 14 to move in the horizontal direction. Since the main body 7 is at the edge of the table body 1, the air intake pipe 14 can be moved along the edge direction of the table body 1 to change the position of the air intake pipe 14.
[0033] The telescopic tube 13 is provided with a plurality of pipes, the diameters of which are gradually reduced, and the pipes with larger diameters can be sleeved on the outside of the adjacent pipes with smaller diameters and sleeved together one by one, so as to change the total length of the entire telescopic tube 13. The plurality of pipes are divided into a vent pipe 17, an extension pipe 19 and a plurality of connecting pipes 20, the diameters of the plurality of connecting pipes 20 are gradually reduced and sleeved together in sequence, the vent pipe 17 is movably connected to the outside of the connecting pipe 20 with the largest diameter, the extension pipe 19 is movably connected to the connecting pipe 20 with the smallest diameter, the other end of the vent pipe 17 is connected to the elbow 12, and the other end of the extension pipe 19 is connected to the intake pipe 14, the telescopic tube 13 can be telescopically adjusted in the horizontal direction to adjust the horizontal position of the intake pipe 14, the direction in which the length of the telescopic tube 13 is adjusted is perpendicular to the direction in which the translation assembly moves, so that the intake pipe 14 can finally be moved in different directions, and the intake pipe 14 is more flexible and changeable to use.
[0034] The adjacent pipes of the telescopic pipe 13 are connected by a fixed collar 22 and a movable collar 23, so that the adjacent pipes are connected to each other to prevent them from falling off. Specifically, the vent pipe 17 and the connecting pipe 20 are both fixed with a fixed collar 22 extending toward the central axis on one end facing the air inlet pipe 14, and the connecting pipe 20 and the extension pipe 19 are both fixed with a movable collar 23 on the outer side of one end facing the elbow 12. The fixed collar 22 and the movable collar 23 at the corresponding positions cooperate with each other to keep the adjacent pipes connected. A circle of rubber pads 31 are arranged on the inner side of the fixed collar 22, and a circle of annular disc 21 is fixed on the inner wall of one end of the vent pipe 17 facing the elbow 12, and a sealing pad 30 is fixedly installed on the inner side of the annular disc 21 to maintain a better sealing effect at the connection.
[0035] Since negative pressure is formed inside the exhaust device 3, external air is sucked into the interior of the pipe, and the telescopic tube 13 is easily affected by the wind pressure and shortens autonomously. In order to avoid the above situation, a non-return mechanism 18 is provided between adjacent pipes to keep the positions of adjacent pipes fixed.
[0036] The check mechanism 18 can be fixed in the following manner: it includes a fixed groove 26, a movable groove 27, a square groove 28 and a fixed plate 29, wherein the fixed groove 26, the square groove 28 and the movable groove 27 are arranged on the inner wall of the pipe and are connected in sequence, the movable groove 27 is distributed along the axial direction of the pipe, the square groove 28 is located at one end of the movable groove 27 facing the intake pipe 14, and the square groove 28 is perpendicular to the movable groove 27; the fixed plate 29 is arranged on the outer surface of the pipe, and the fixed plate 29 extends into the movable groove 27 on the inner wall of the adjacent pipe, and the fixed plate 29 moves in the movable groove 27, the square groove 28 and the fixed groove 26; when in use, it is only necessary to pull the pipe out to the outermost part, and then rotate the pipe with a smaller diameter so that the fixed plate 29 enters the fixed groove 26 through the square groove 28, and is limited by the fixed groove 26, so that the pipe with a smaller diameter is prevented from shrinking to the inside of the adjacent pipe, and the supporting effect of the telescopic tube 13 is maintained.
